Lower overhead fault-tolerant building blocks for noisy quantum computers
Prithviraj Prabhu
Quantum computation holds the promise of solving certain complex problems exponentially faster than classical computers. However, the high prevalent noise in current quantum device…
Short two-qubit pulse sequences for exchange-only spin qubits in 2D layouts
Jason D. Chadwick, Gian Giacomo Guerreschi, Florian Luthi +9
Exchange-only (EO) spin qubits in quantum dots offer an expansive design landscape for architecting scalable device layouts. The study of two-EO-qubit operations, which involve six…
New magic state distillation factories optimized by temporally encoded lattice surgery
Prithviraj Prabhu, Christopher Chamberland
Fault-tolerant quantum computers, with error correction implemented using topological codes, will most likely require lattice surgery protocols in order to implement a universal ga…
Distance-four quantum codes with combined postselection and error correction
Prithviraj Prabhu, Ben W. Reichardt
When storing encoded qubits, if single faults can be corrected and double faults postselected against, logical errors only occur due to at least three faults. At current noise rate…
Fault-tolerant syndrome extraction and cat state preparation with fewer qubits
Prithviraj Prabhu, Ben W. Reichardt
We reduce the extra qubits needed for two fault-tolerant quantum computing protocols: error correction, specifically syndrome bit measurement, and cat state preparation. For distan…
Influence of coin symmetry on infinite hitting times in quantum walks
Prithviraj Prabhu, Todd A. Brun
Classical random walks on finite graphs have an underrated property: a walk from any vertex can reach every other vertex in finite time, provided they are connected. Discrete-time…
Testing of flag-based fault-tolerance on IBM quantum devices
Anirudh Lanka
It is hard to achieve a theoretical quantum advantage on NISQ devices. Besides the attempts to reduce error using error mitigation and dynamical decoupling, small quantum error cor…
Efficient experimental design of high-fidelity three-qubit quantum gates via genetic programming
Amit Devra, Prithviraj Prabhu, Harpreet Singh +2
We have designed efficient quantum circuits for the three-qubit Toffoli (controlled-controlled NOT) and the Fredkin (controlled-SWAP) gate, optimized via genetic programming method…
